SPECIFICATION forming part of Letters Patent No. 508,683, dated November'14, 1893.

Application filed May Z5, 1892..- Serial No. 434,240. (No model.)

To @ZZ whom it may concern,.-

Be itknown that I, WILLIAM B. COLLINS, a citizen of the United States,residing at Santa Rosa, in the county of Daviess and State of Missouri,have invented a new and useful Improvement in Windmills, of which thefollowing is a specification.

This invention relates to certain new and useful improvements in windmills; and itl consists substantially in such features of construction,arrangement, and combinations of parts as will be hereinafter moreparticularly pointed out.

The object of the invention is to provide a simple and reliable form ofwind mill for working the piston or sucker rod of pumps and similarclasses of machinery, substantially as will be more fully hereinafterset forth, whentaken in connection withthe accompanying drawings, inwhich- Figure 1 representsan elevation of a wind wheel or mill embodyingmy improvements; Fig. 2 is atop or plan view thereof. Fig. 3 is aVertical sectional view, taken on the line xof Fig. l, and Fig. 4 is adetailed per-i spective view of the spring which tends tov hold the millto the wind.

In carrying my invention into eect I provide the usual turn table uponwhich is mounted the vertical support in the top of which the mainoperating shaft has its bearings; the said shaft being geared to the ec-`centric rod which operates the vertically reciprocating piston orsucker rod of a pump or other similar contrivance. Suitably secured to asupport, and projecting out beyond the wind wheel and at v'substantiallyright angles to the axis of rotation thereof is a rigid storm vane; andsuitably mounted upon a pivotal support is a larger regulating vane withwhich is combined a spring which tends to hold it with a yielding forcein rear of and parallel with the axis of the `wind wheel. Combined withthe said spring are means whereby its effective tension or force, whileacting upon the regulating vane, can be varied in order to suit thevarying requirements of the mill.

Referring-to the drawings, A represents the usual turn-table and B, Btwo parallel vertical supports mounted'thereon. 'I

which, as shown, is conical and is surrounded Aby la-,spiral blade a.

D represents the main operating shaft having bearings in the top of thesupports B, B, and connected with the wind wheel. This shaft lisprovided with a small pinion b which meshes with a gear wheel c carriedon a rod Yor shaft cl, which in turn carries the eccentric,

E designates the storm vane which extends rigidly out at substantiallyright angles to is pivotally supported upon a shaft g close in vrear. ofthe wind wheel. A hook or catch/i projects from oneof the supports B andwith itthe swinging or regulating vane F can be made to engage when itis desired that the latter should be secured in line with the wind wheelso as to hold the latter into the wind so as to be acted upon by thefull force of the same. The regulating vane can be released from thehook or catch t' in a manner to be presently described, and when soreleased it is necessary that it should be held with a yielding force ina position in rear of the wind wheel or else the storm vane will carrythev parts of the apparatus around so that vanes E and F lie parallel toeach other and with the wind wheel out of operative position. Thisyielding device which tends to hold the regulating vane in position tocarry the-Wiudwheel 'into the wind, consists of a spring H. This springis of curved or bowed shape, and its ends are preferably slightlynotched and have an interlocking engagement with the notched plate m,rm., which are carried, one by the swinging regulating vane, and theother by one of thesupports B. As will be understood this spring tendsto draw the swinging vane F aroundso that it lies against the supports Band in line with the wind wheel. The plates m are notched along theiredges, as at n, n and., by changing the ends of the spring from onenotch to another, the effective force thereof can be changed. This willbe understood from the factthat when the spring is close to the pivotAthe axis of the wind wheel; and F represents Athe larger swinging orregulating vane which IOO g of the swinging vane it acts with less forcethan when it is farther therefrom.

The means whereby the swinging or regulating vane can be released fromthe catch or hook t' consist of a reciprocating rod Gwhich extends froma point where it can be conveniently operated by the attendant upwardthrough the turn-table, and a link or links 0 connecting thereciprocating rod with the swinging vane, preferably by a swivelconnection. By lifting or pushing upward upon the rod G the regulatingvane will be carried upward suiiieiently far to rise over the point ofthe hook or catch t'. The inclination of the links o is such that whenthey are moved upward the direction of the force which is imparted tothe regulating vane is such asu to cause it to be moved outward or awayfrom the supports b suliciently far to clear the hook, when the vane canbe allowed tofall again and will, in such case lie outside of the saidhook and will be free to swing except so far as it is controlled by thetension of the spring II.

Vhen the wind is light and steady the reg-lr lating vane can-be made toengage withA the hook or catch t so that the wind wheel willbe held intothe wind and be operated with the full force of the latter. If howeverthe wind shouldinerease in force or become `sovariable as to endangerthe mill, by reason of the regulating vane being held rigidly to thesupports the spring carries the wind wheel back into the 'wind again, aswill be understood.

Should it be desirable to stop entirely the operation of the wind wheelthis can be done by removing the spring when the wind will carry the twovanes, E and F, alongside of` each other with the wind wheelout of thewind and so that it will not be operated thereby.

It will be under-` It will be seen from the foregoing description thatthe mill which I have invented is simple in construction and effectivein its operation and is of such a nature as not liable to easily get outof repair.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a wind mill, the combination of the wind wheel, the storm vane,the larger swinging regulating vane, and the bowed spring II interposedbetween the swinging vane and a fixed part of the mill, and tending tokeep the swinging vane in line with the wind wheel and at substantiallyright angles to the storm vane, substantially asdescribed.V

2. In a wind mill, the combination" of the wind wheel, the stormvane,th`e swinging-regulating vane, the spring which tends to hold theregulating vanef in' line with the' wind wheel, and connected therewithand with some fixed part of the mill', and the meansfor adjusting thepoints-of connection of the said spring whereby its eftectnpon theregulating vane can-'be varied, substantially as setforth.

3. In a windt` mill,the' combination off the f wind wheel, the stormvane,-the^larger swinging regulating vane, the notched plates rm/ntcarried, one by a xedpart of the mill, and the other by theregi'llating` vane, the bowed spring II which engages with the saidnotched plates,- and tendsi to hold'f the regulating vane in linewiththewind wheel, the hook or-'catch 1I which is adapted to hold theregulating vane in line with thewind w'heehandj the' WILLIAM B. COLLINS.
